Google just released Android aka Open Handset Alliance.
Well, yes, everyone knows that.
But it is not something new. It is something Google had acquired as part of Android Inc. and they have been working on it since then.
But there is a problem. Is it fighting against Handset makers or the carriers or both? Well, it did get support from T-mobile and few others. But those are not the only company in the world. Even if they can not get AT&T and Verizon to sign up, there are many others (well they did get China Mobile) such as Reliance of India, Hutch Worldwide, Airtel Worldwide etc.
But one thing is for sure. It does give Linux Kernel plenty of credibility as a backbone of a Mobile Operating System (Yes, Linux is not an operating system, but just the Kernel).
